General Description
The AS5030 is a contactless magnetic rotary encoder for accurate angular measurement over a full turn of 360°. It is a system-on-chip, combining integrated Hall elements, analog front end and digital signal processing in a single device.
To measure the angle, only a simple two-pole magnet, rotating over the center of the chip is required.
The absolute angle measurement provides instant indication of the magnet’s angular position with a resolution of 8 bit = 256 positions per revolution. This digital data is available as a serial bit stream and as a PWM signal.
In addition to the angle information, the strength of the magnetic field is also available as a 6-bit code.

KEY FEATUREs
• 360°contactless angular position encoding
• Two digital 8-bit absolute outputs:
    - Serial interface and
    - Pulse width modulated (PWM) output
• User programmable zero position
• High speed: up to 30,000 rpm
• Direct measurement of magnetic field strength allows exact determination of vertical magnet distance
• Serial read-out of multiple interconnected
    AS5030 devices using daisy chain mode
